Description
Verfahren zum Entzug des Sauerstoffs aus der Luft in geschlossenen Behältern, insbesondere zwecks Konservierung von Nahrungsmitteln Es ist schon vorgeschlagen worden, fäulnisempfindliche Stoffe, wie Lebensmittel, zu konservieren, indem man sie in luftdicht geschlossenen Behältern zusammen mit Substanzen aufbewahrt, die den Sauerstoff der Luft absorbieren bzw. verbrauchen, wodurch die Lebenstiätigkeit der aeroben Kleinlebewesen verhindert wird. Diese Verfahren haben jedoch den Nachteil, daß die Sauerstoffentzieher, z. B. gewisse Öle, nur eine langsame Entfernung des Sauerstoffs gestatten. Man hat den Sauerstoff auch schon durch Verbrennen von Stoffen, z. B. Alkohol, entfernt. Diese Verfahren sind jedoch umständlich. Auch hat man schon vorgeschlagen, in die zur,Aufbewahrung der Lebensmittel bestimmten Räume Chemikalien einzubringen, die den Sauerstoff rasch verbrauchen. Solche schnell reagierenden Sauerstoffentzieher mußte man jedoch erst unmittelbar vor dem Gebrauch zubereiten.Process for the removal of oxygen from the air in closed Containers, especially for the purpose of preserving food. It has already been proposed been used to preserve putrefactive substances, such as food, by they are kept in airtight containers together with substances that absorb or consume the oxygen in the air, thereby increasing vital activity the aerobic microorganisms is prevented. However, these methods have the disadvantage that the oxygen scavengers, e.g. B. certain oils, only a slow removal of the Allow oxygen. You already have oxygen by burning substances, z. B. alcohol removed. However, these procedures are cumbersome. One already has suggested that chemicals should be placed in the rooms intended for the storage of food to bring in, which use up the oxygen quickly. Such quick-reacting However, oxygen scavengers only had to be prepared immediately before use.
Gemäß der Erfindung versieht 'man nun solche schnell reagierenden Stoffe mit Schutzmitteln, welche erst beim Gebrauch, insbesondere bei Zutritt von Feuchtigkeit, die Oxydation gestatten. Derartige Schutzmittel sind Sägespäne, Holzmehl, Torfstreu o. dgl. Beim Aufsaugen von Wasser quellen die Schutzmittel und ermäglichen so den Zutritt des Sauerstoffs und der Feuchtigkeit zu dem Sauerstoffverbraucher. Die Gemische werden zweckmäßig mit Bindemitteln, wie Gummiarabicum, Zucker o. dgl., in Tablettenform gepreßt. Der Sauerstoffentzieher kann auch mit einer dünnen Haut eines erst durch die Einwirkung der Feuchtigkeit im Konservierungsbehälter sich lösenden Stoffes, wie Gelatine, überzogen werden.According to the invention, one now provides those that react quickly Substances with protective agents, which only when used, especially when approaching Moisture that allow oxidation. Such protective agents are sawdust, wood flour, Peat litter or the like. When water is sucked up, the protective agents swell and make it possible so the access of oxygen and moisture to the oxygen consumer. The mixtures are expediently combined with binders such as gum arabic, sugar or the like. compressed in tablet form. The oxygen scavenger can also be used with thin skin one only through the action of moisture in the preservation container solvent, such as gelatin, are coated.
Auf solche Weise kann man mit Stoffen arbeiten, die ein rasches Entfernen des Sauerstoffs sicherstellen.In this way one can work with substances that can be removed quickly of oxygen.
Als Sauerstoffentzieher sind beispielsweise Eisenpulver, Ferrosulfat o. dgl. geeignet. Auch kommen Alkali- oder Erdalka hmetalle. weiterhin leicht oxydierbare Öle, die in klei. nen, luftdicht geschlossenen Behältern eingeschlossen sind, in Frage.Iron powder, ferrous sulfate, for example, are used as oxygen scavengers or the like. Suitable. Alkali or alkaline earth metals are also used. still easily oxidizable Oils that come in small. enclosed in airtight containers Question.
Die Menge des Sauerstoffentziehers in den Kapseln oder Tabletten wird vorteilhaft auf eine bestimmte Menge Luft bemessen.The amount of deoxidizer in the capsules or tablets will be advantageously dimensioned for a certain amount of air.
Selbstverständlich kann man den Sauerstoffentziehern auch solche Stoffe,
die imstande sind, etwaige bei der Reaktion des Entziehers auftretende üble Gerüche
zu absorbieren, z. B. aktive Kohle oder desinfizierende Stoffe, beimischen.
Ausführungsbeispiele
In Gelatinekapseln eingeschlossen oder mit einem wasserlöslichen Überzug versehen
werden z. B. folgende Mischungen angewendet:
Die in den letzteren Beispielen angeführten Mischungen werden mit einem Zusatz kleiner Mengen geeigneter Bindemittel, z. B. Gummiarabicum, zu Tabletten gepreßt.The mixtures listed in the latter examples are with an addition of small amounts of suitable binders, e.g. B. gum arabic, into tablets pressed.
Beim Gebrauch bringt man die Tabletten, gegebenenfalls in zerkleinertem Zustand, auf eine feuchte Unterlage, woraufhin die Reaktion sofort beginnt.In use, the tablets are brought, if necessary in crushed form State on a damp surface, whereupon the reaction begins immediately.
